Proclaim Guarantee only lasts 20 years?

[unmerged(225264)]

I proclaimed a guarantee on Gotland after it became independent from DK. I thought this would bring me into a lot of juicy wars where my navy could capture some ships and slowly eat DK. That worked fine. A bit too well actually as now Sweden has taken a bite at DK too and then swallowed half of Norway. No sooner had they signed peace did they declare war on Gotland. Fine, I thought.
But then, no Call to Arms from Gotland, my guarantee has vanished into thin air. Looking back in save files I conclude that my guarantee has expired after 20 years.

Any other diplomatic actions that are time bound?

Warnings also last only 20 years.
In the HttT expansion an option which is halfway between a guarantee and a vassal is a 'Sphere of Influence' over the country (which costs 10 prestige to declare). A SoI does not expire and gives you a CtA like a guarantee and also gives you a CB on any other country that forms a diplomatic tie with them ('violating your sphere'). They can leave your SoI if they get too powerful though.

only 20 years? Damn, how many times havn't i wished it only lasted 10... or 5. It's all good when you're the guarantee, but try being small tuscany trying to expand, when big scary Austria has guaranteed everyone else -.-

Ignoring a call to arms from countries in your Sphere of Influence also doesn't cost any prestige, unlike alliances/guarantees. Definitely the way to go if you are much larger than the country you're adding.

Yea, anytime your about to sign a peace deal and have 100 prestige already and spare diplos throw out some SoIs.

You're right.... Why on earth didn't i think of that?? (Face to palm.......)

Well, guarantee can slowly increase the relation between 2 countries, but the SOI will not. Also, once a nation is in your SoI, you can no longer guarantee them (existing guarantee still disappear after years), which is why sometimes I would rather guarantee someone's independence if I wish to diplomatic-vasslize or making/maintaining a personal union.

Btw, you may not want to lose too much of your prestige cuz the junior members in personal union may insult you if they have more prestige.
